Mechanical Design & Analysis of RF Structures

The Berkeley Lab has developed methodology and expertise in the analysis, design and fabrication of RF cavities for a variety of applications. Numerous normal conducting copper cavities have been developed for use as accelerating structures for particle accelerator beamlines. We have extensive experience designing, building and operating both pillbox type cavities and radio-frequency quadrupoles (RFQ’s) that operate over a wide range of resonant frequencies. The primary software tools used for the design and analysis of the cavities are CST Microwave Studio and ANSYS. Fabrication of the cavities are carried out in our shops with specialized procedures such as hydrogen brazing, e-beam welding and cooling passage gun-drilling being provided by selected local vendors.
